Ashoka ,the most famous of all Mouryan rulers,was the first king to unify India.He invaded Kalinga but after the war of Kalinga,Ashoka turned away from war and adopted the policy of Dhamma. There were a number of problems that troubled Ashoka while introducing Dhamma. People in the empire followed different religions and this sometimes led to conflict. Animals were sacrificed. Slaves and servants were ill-treated. There were quarrels in the family and among the neighbours.This policy was meant to bring the people of his empire together and inculcate in them a sprit of tolerance,non-violence,and respect for each other.He felt it was his moral duty to solve the problems of his subjects.

area = L X B = 4 x 8 = 32 cm2

Perimeter = 2x( L +B)

=2x(4 +8) =2 x 12 =24 cm

No.

The victims of the Bhopal gas tragedy got some monetary compensation. But money cannot substitute for a near and dear one who may have lost his life in the tragedy. Many people who were maimed for life have no use for the compensation money. Hence, it can be said that the victims of the Bhopal gas tragedy did not get justice.

In {tex}\triangle {/tex}YCB , we have
{tex}\tan 45 ^ { \circ } = \frac { B C } { Y C }{/tex} 
{tex}1 = \frac { x } { Y C }{/tex}
YC = xm 
{tex}\Rightarrow {/tex} XA = x m
In {tex}\triangle {/tex}XAB, {tex}\tan 60 ^ { \circ } = \frac { A B } { X A }{/tex} 
{tex}\sqrt { 3 } = \frac { x + 40 } { x }{/tex}

{tex}\sqrt { 3 } x = x + 40{/tex}
{tex}x \sqrt { 3 } - x = 40{/tex} 
{tex}x = \frac { 40 } { \sqrt { 3 } - 1 } \times \frac { \sqrt { 3 } + 1 } { \sqrt { 3 } + 1 }{/tex} 
{tex}= 20 ( \sqrt { 3 } + 1 ){/tex} 
{tex}= ( 20 \sqrt { 3 } + 20 ){/tex} 
{tex}\therefore {/tex} height of the tower AB = x + 40
{tex}= 20 \sqrt { 3 } + 20 + 40{/tex} 
{tex}= 20 \sqrt { 3 } + 60{/tex}
{tex}= 20 ( \sqrt { 3 } + 3 ){/tex}
In {tex}\triangle {/tex} XAB, 
{tex}\sin 60 ^ { \circ } = \frac { A B } { B X }{/tex}
{tex}\frac { \sqrt { 3 } } { 2 } = \frac { A B } { B X }{/tex} 
{tex}B X = \frac { 20 ( \sqrt { 3 } + 3 ) 2 } { \sqrt { 3 } }{/tex} 
{tex}= 40 ( \sqrt { 3 } + 1 ){/tex}
{tex}= 40 \times 2 \cdot 73{/tex}
= 109.20 m

They are caused by sudden movements of the Earth's tectonic plates.The sudden release of tension in the tectonic plates sends waves of energy that travel through the Earth.

Plants absorb water from the soil and evaporates it to form clouds. Deforestation leads to cutting down of trees. As a result less water is absorbed from the soil and it disturbs the water cycle. The formation of clouds become difficult which leads to reduced rainfall.
